What is "hbb"

HBB

Beta globin (also referred to as HBB, β-globin, haemoglobin beta, hemoglobin beta, or preferably haemoglobin subunit beta) is a globinprotein, which along with alpha globin ( HBA), makes up the most common form of haemoglobin in adult humans, the HbA. It is 146 amino acids long and has a molecular weight of 15,867 Da. Normal adult human HbA is a heterotetramer consisting of two alpha chains and two beta chains.

HBB is encoded by the HBB gene on human chromosome 11. Mutations in the gene produce several variants of the proteins which are implicated with genetic disorders such as sickle-cell disease and beta thalassemia, as well as beneficial traits such as genetic resistance to malaria.
